My DS is 8mo and is constantly described as serious. He smiles and giggles loads at home with me and DH but when strangers coo at him he just gives them a cold, hard stare which reminds me of DH. He makes good eye contact with everyone, just doesn't smile on cue. If he spends more than an hour with someone, he'll maybe start smiling.
I haven't been worried about it, and have been offering the reply "well, these are serious times we are living in" which usually fails to get a laugh. But today, I overheard one of the other mum's from our little group saying "see, he doesn't smile" to someone.
Should I be worried? I always assumed it was because he's a bit clingy and the fact both my husband and I are pretty reserved. But now I've gone all paranoid about it.
